Multi-mode transmitter having adaptive operating mode control

A transceiver apparatus, comprising:

• a transmitter configurable to operate in a plurality of operating modes;
• a receiver;
• a plurality of look up tables (LUTs);
• and
• an operating mode controller configured to receive an indication of a transmit power said transmitter is to transmit and control which operating mode of said plurality of operating modes said transmitter is to operate,
• wherein said transmitter is configurable to transmit in a plurality of transmit frequency bands, said receiver is configurable to receive in a plurality of receive frequency bands, and said operating mode controller is configured to control which operating mode of said plurality of operating modes said transmitter is to transmit depending on which transmit frequency band of said plurality of transmit frequency bands said transmitter is configured to transmit and which receive frequency band of said plurality of receive frequency bands said receiver is configured to receive,
• wherein said LUTs are configured to correspond to a plurality of transmit frequency band and receive frequency band pairs, wherein said plurality of operating modes is mapped into each of said LUTs in relation to receive powers of said receiver and transmit powers of said transmitter and in a manner dependent upon levels of frequency separation between each of the transmit frequency band and receive frequency band pairs, and
• wherein said operating mode controller is configured to access a LUT from among said plurality of LUTs depending on which transmit frequency band of said plurality of transmit frequency bands said transmitter is configured to transmit and which receive band of said plurality of receive bands said receiver is configured to receive.
